Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Historical observations

Barnard, E.E. (1883)

See A new Nebula near phi Virginis. Astron. Nachr., 104, 285.

1881 July 27 I found a faint Nebula 1° 48' north and 5m39s west of φ Virginis (as determined by the aid of the finder). Upon inquiring I found that no nebula was known at that point: On account of its approach to the sun nothing more was done about it until July of 1882 when being certain of its existence I notified Harvard Observatory and Mr. O.C. Wendell very kindly observed it with the 15 inch equatorial, making its mean position for 1882.0:

RA =14h16m19.6s

Dec = +0°  9' 14"

He describes it as being »Rather diffuse and faint, but gradually a little brighter in the middle.«

Nashville Tenn., 1883 January 8.

Barnard, E.E. (1884)

See New nebulae - Small black hole in the milky way - Duplicity of beta-1 Capricorni. Astron. Nachrichten, 108, 369-372.

object "d" "Faint nebula. The position was obtained by Mr Wendell at Harvard College Obs. He describes it (with the 15-inch refractor) as being 'rather diffuse and faint, but gradually a little brighter in the middle'. The place is for 1882.0 This nebula has before been announced, and examined by, among others, Mr Temple and is here inserted merely as a matter of record."

Published comments

Worssell, W.M. (1914)

W. M. Worssell, in Union Observatory Circular No 20 (1914), comments on objects seen on photographic plates taken with the Franklin-Adams Star-Camera. He notes: "Very fine large spiral nebula, 9 mag., with two nuclei. Canes Ven. nebula type."

Sulentic & Tifft (1973)

(Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads IRRR,VDIF,COMPLKNSTR.

Sandage, A. et al. (1975) Galaxies and the Universe

G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes "Includes the NGC 5566 & NGC 5713 group." The five brightest members of the Virgo III cloud are NGC 5566, NGC 5746, NGC 5713, NGC 5701 & NGC 5584.
